Ukraine's air force said Russia targeted several regions overnight with 267 drones, of which around 200 were Shahed attack drones and the rest decoys. The air force said it shot down or otherwise suppressed 244 drones. Twenty-three drones impacted across seven locations, with falling debris reported in nine locations, the air force said.
